Exploring Teacher Leadership’S Effect On Teacher Burnout: Does School Rurality Make A Difference?, Jiangang Xia, Sam Butler

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In literature, both teacher leadership and teacher burnout have been heavily studied. However, it is unknown to what extent teacher leadership makes a difference in teacher burnout, and whether school rurality makes a difference in between. This study fills the research gaps by conceptualising teacher leadership from both instructional and non-instructional dimensions and applying a quantitative method to large-scale national data. Findings revealed that (a) rural teachers presented higher levels of teacher leadership practices; (b) rural and non-rural teachers presented the same levels of burnout; and (c) both instructional and noninstructional dimensions of teacher leadership practices helped reduce teacher burnout …

Scooting To A Brighter Tomorrow: Shared E-Scooters And Their Use In Lincoln, Nebraska, Tanner J. Hiemer

Community and Regional Planning Program: Theses

As a recent addition to our transportation systems, shared e-scooters have the potential to improve how people travel in the urban environment. While there is a lot to be hopeful about, the relative novelty of e-scooters calls for closer examination of how they interact with the built environment and other modes of transportation. Additionally, the equity of shared e-scooters must be at the forefront of discussion when considering their utility in the future. Given their flexibility in use, e-scooters could fill spatial gaps in transportation systems and provide improved mobility to those who are most transportation disadvantaged. This research aims …

Attitudes Of Experiential Designers Across Design Disciplines, Danielle Degarmo

Architecture Masters of Science Program: Theses

The expanded use of the term scenography is widening its understanding of the word to encompass many experiential design disciplines beyond its origin in theatre. At its essence, scenography is the culmination of a designer’s collaborative efforts to take a prompt, whether it be a client program, a script, or other, and produce a holistic assemblage of experiential design elements to spatially engage an end user. Many experts in across design fields have acknowledged that there is disciplinary cross over among those practicing in experiential design fields in terms of design output or intention. By means of designer surveys and …

Habitat Heterogeneity In Nebraska Streams And Distribution Prediction For Tier-1 Cyprinids Using Multi-Scale Modeling Of Fluvial And Landscape Features, Connor P. Hart

School of Natural Resources: Dissertations, Theses, and Student Research

Multiscale environmental processes determine in-stream habitat conditions which drive species distributions. Habitat constitutes the physical template upon which ecological processes occur and species conduct life stage activities. Habitat heterogeneity promotes biodiversity of aquatic systems. Stream classification informs freshwater conservation by providing a useful framework to account for habitat heterogeneity, often based on landscape regions of similar environmental processes. A greater understanding of landscape-based classification frameworks as means to classify stream systems may improve understanding of drivers of biodiversity. Using Nebraska as a case study, on a statewide scale, objectives were 1) to characterize habitat availability for several at-risk fish species, …

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Traditionally, traffic prediction has been an engineering challenge due to insufficient quantities of data. In this thesis, the use of a new type of data called location-based service (LBS) data from StreetLight (StL) and a large database of multi-modal traffic counts are used to infer vehicle, pedestrian, and bicycle volumes on all road segments in Lincoln, Nebraska. Additional land use features are incorporated into the model from the EPA Smart Location Database (EPA-SLD). The use of random forest models provides strong measures of fit for all modes, with R² scores of 0.98 for both the bicycle and pedestrian modes …

Using Genetic Comparisons Of Populations From Arizona, Mexico, And Texas To Investigate Fall Armyworm Migration In The American Southwest, Rodney N. Nagoshi, Ashley E. Tessnow, Yves Carrière, Jeff Bradshaw Dr., Kyle Harrington, Gregory A. Sword, Robert L. Meagher

Department of Entomology: Faculty Publications

Fall armyworm (FAW) is a global agricultural pest, causing substantial economic losses in corn and many other crops. Complicating efforts to control this pest is its capacity for long distance flights, which has been described in greatest detail for the central and eastern sections of the United States. FAW infestations are also routinely found in agricultural areas in southern Arizona, which lie beyond the western limits of the mapped migratory pathways. Climate suitability analysis found that the affected Arizona locations cannot support permanent FAW populations, indicating that these FAW most likely arise from annual migrations. A better understanding of this …

Drought In The Breadbasket Of America And The Influence Of Oceanic Teleconnections, Olivia G. Campbell, Gregory B. Goodrich

School of Natural Resources: Faculty Publications

From 1980 to 2020, drought events accounted for only 11.4% of the billion-dollar disasters in the United States (U.S.), yet caused the second-highest total amount in damages, at USD 236.6 billion. With the average cost of a drought being upwards of USD 9.5 billion, these natural disasters can create serious problems in agriculture. Drought is defined as a period of below-average precipitation that causes damage to agriculture and water supplies. Previous research has linked drought events in the U.S. Great Plains to oceanic teleconnections in the Pacific and Atlantic basins, indicating the influence of El Niño—Southern Oscillation (ENSO), the Pacific …

An Analysis Of Racially Disparate Impacts On Housing For The City Of Tukwila, Washington, Neil Tabor

Community and Regional Planning Program: Professional Projects

The housing crisis within the Pacific Northwest of the United States has prompted action from Washington legislators, resulting in Governor Inslee identifying housing as a key priority and the legislature passing a number of forward-thinking bills in the last half decade, requiring the allocation of more resources, and asking more of jurisdictions to address current housing needs and anticipated future growth. Layered within the planning efforts for future growth are concerns and considerations for the potential of new housing development to perpetuate and exacerbate societal inequities built on discriminatory housing policies and practices of generations past and present. In an …

A Climatology Of Mesoscale Airmasses With High Theta-E, Charles J. Kropiewnicki

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

A Mesoscale Airmass with High Theta-E (MAHTE) is a narrow region of larger theta-e located on the cool side of an airmass boundary. MAHTEs typically possesses higher CAPE than the warm side of the boundary, creating a more favorable environment for severe convection. MAHTEs can also be characterized by larger low-level shear and lower LCLs and may also have a propensity for supporting tornadogenesis. The majority of MAHTE research to date has been comprised of case studies, and the prevalence of MAHTEs is not well understood. This project fills that knowledge gap by creating a climatology of MAHTE occurrence. This …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Wetlands are responsible for 20%–31% of global methane (CH4) emissions and account for a large source of uncertainty in the global CH4 budget. Data-driven upscaling of CH4 fluxes from eddy covariance measurements can provide new and independent bottom-up estimates of wetland CH4 emissions. Here, we develop a six-predictor random forest upscaling model (UpCH4), trained on 119 site-years of eddy covariance CH4 flux data from 43 freshwater wetland sites in the FLUXNET-CH4 Community Product. Network patterns in site-level annual means and mean seasonal cycles of CH4 fluxes were reproduced accurately in tundra, boreal, and temperate regions (Nash-Sutcliffe Efficiency ∼0.52–0.63 and 0.53). …

Turnover, Megan Paul, Sarah Stepanek

Umbrella Summaries

What is turnover?

The definition of turnover tends to somewhat vary in practice and research. The most common element is an employee leaving their job. Beyond that, turnover can be further defined as internal vs. external, voluntary vs. involuntary, functional vs. dysfunctional, and avoidable vs. unavoidable.

• Internal vs. external: Internal turnover means that the employee moves to a different job within the organization, whereas external means that the employee leaves the organization altogether. In child welfare, however, the “organization” may be defined as all of state or county government, which means that a lot of movement is considered internal.
• Voluntary …

The Pepsis Menechma Lepeletier (Hymenoptera: Pompilidae: Pepsinae) Taxonomic And Nomenclatural Problem, Frank E. Kurczewski

Insecta Mundi

Hurd (1952), in revising the Nearctic species of Pepsis Fabricius, separated P. cerberus Lucas from P. elegans Lepeletier based on external morphology and geography. Vardy (2005), in his Western Hemisphere Pepsis revision, combined these taxa and several Neotropical color and structural variants in a broad defini­tion of P. menechma Lepeletier extending across ~11,250 km and two continents. Vardy (2005) synonymized the familiar and well-documented, 160-year-old P. elegans under P. menechma probably because it appeared several pages later in Lepeletier’s (1845) Histoire Naturelle des Insectes. Hyménoptères. Vardy’s (2005) interpre­tation of Pepsis menechma as a viable species presents a taxonomic and …

Climate Change Impacts And Adaptation To Permafrost Change In High Mountain Asia: A Comprehensive Review, Prashant Baral, Simon Allen, Jakob F. Steiner, Tika R. Gurung, Graham Mcdowell

Department of Earth and Atmospheric Sciences: Faculty Publications

Changing climatic conditions in High Mountain Asia (HMA), especially regional warming and changing precipitation patterns, have led to notable effects on mountain permafrost. Comprehensive knowledge of mountain permafrost in HMA is mostly limited to the mountains of the Qinghai-Tibetan Plateau, with a strong cluster of research activity related to critical infrastructure providing a basis for related climate adaptation measures. Insights related to the extent and changing characteristics of permafrost in the Hindu Kush Himalaya (HKH), are much more limited.

Mtco1-Based Population Structure And Genetic Diversity Of Pacific Oyster Crassostrea Gigas Populations Acquired From Two Farms In South Korea, Thanh T. Biet, Su-Jin Park, Hong-Keun Park, Dongjin Park, Youn-Hee Choi

Department of Food Science and Technology: Faculty Publications

Since the early 1990s in South Korea, climatic and anthropogenic factors have incurred the reduction of the wild seeds of the Pacific oyster, Crassostrea gigas, which raised concerns about losing genetic diversity and accelerating genetic deterioration. We assessed the genetic diversity of C. gigas populations from two farms (Tongyeong and Gadeokdo) on the southern coast, where about 80% of the cultivated oysters in Korea are produced. Tongyeong showed slightly higher diversity than Gadeokdo, but both populations had a similar genetic structure characterized by low nucleotide diversity. Comparative haplotype analyses provided data supporting genetic features of the populations that include …

Higher Education Exports Before And After Covid, John C. Beghin, Byungyul Park

Yeutter Institute International Trade Policy Review

Historically, the higher education system in countries belonging to the Organization for Economic Cooperation and Developing (OECD), a grouping of advanced economies, and especially in the United States, has been a magnet for foreign students, both graduate and undergraduates. Graduate students tend to be supported by teaching and research assistantships from the hosting university and do not generate direct revenues for the hosting institution. They do contribute to the economy with their productivity in research projects and with their private consumption. In contrast, most undergraduate foreign students pay fees and tuition which are often higher than those paid by local …
